Abstract: Images sensed through object lenses 100R and 100L, having zoom lenses, with image sensors 102R and 102L are processed by image signal processors 104R and 104L, and an image of an object in each of the sensed images is separated from a background image on the basis of the processed image signals. The separated image signals representing the image of the object enter the image processor 220, where a three-dimensional shape of the object is extracted on the basis of parameters used upon sensing the images. The parameters are automatically adjusted so that images of the object fall within the both image sensing areas of the image sensors 102R and 102L and that they fall within the both focal depths of the image sensors 102R and 102L.

Abstract: In a head-mount display apparatus with which an observer can observe images displayed on display units arranged in correspondence with the right and left eyes of the observer while wearing the apparatus on his or her head, first and second image display ranges are defined on each display unit. An angular velocity detection unit detects the displacement of the head of the observer, and changes the positions of the first and second image display ranges on the display units relative to each other on the basis of the detected displacement information of the head. As a result, a natural display corresponding to the movement of the head can be attained in real time even under the condition of a limited image memory capacity.

Abstract: Timing signal generators 24R and 24L, simultaneously initialized, synchronize image-sensing devices 21R and 21L with each other. Video signal processors 23R and 23L process the synchronized image signals, from the image sensing devices 21R and 21L, to obtain partial image signals from the synchronized image signals. The partial image signals are converted, using a Gate 29 and a memory 27, into a single-system image signal, in which the partial image signals are arranged in a horizontal direction within one field. Thus, an image signal having well-balanced horizontal and vertical resolutions is outputted. This allows ordinary VTR recording and reproduction.
